CARBON NEGATIVE
Avoidance, Mineralisation, Reduction.
A DROP IN SOLUTION
Little to no changes required to current manufacturing and construction processes.

INSULATING PROPERTIES
Has a higher heat capacity than typical mineral lightweight aggregates.

STRENGTH
Has comparable strength to typical lightweight aggregates.

SUPPORTS CIRCULAR ECONOMY
Made from a combination of waste materials, including those from outside the construction sector.

LIGHTWEIGHT
50% lighter than traditional aggregates.
The process involved in making concrete is responsible for 8% of the planet's CO2.
After water, concrete is the most widely used substance on earth.
Decarbonising carbon-intensive materials is a huge challenge for the construction sector but is of vital importance, especially with net-zero targets on the horizon.
OSTO® is carbon negative and can lower the carbon footprint of concrete by:
(1) Avoidance
OSTO® is made of waste products that would be incinerated.
Low Carbon Materials prevents this waste being burnt which would immediately release harmful greenhouse gases into the atmosphere.
(2) Mineralisation
OSTO® sequesters and stores CO2 in the aggregate, and therefore locks it within the resulting concrete permanently.
(3) Reduction
OSTO® reduces the reliance on traditional carbon intensive lightweight aggregates, therefore, enables construction firms to replace carbon-intensive materials in their value chain.
OSTO® is a carbon-negative lightweight aggregate with broad application potential, including use in concrete mixes, screeds and resin-bound applications.
OSTO® can be used in a variety of concrete applications. Customers should check that the product's properties are suitable for their specific application prior to use.
Depending on performance and carbon targets, a notional replacement of OSTO® within bound construction materials is likely to be in the order of 3 to 15%. However, a testing ladder substituting OSTO® for aggregate is recommended to ensure that optimum design is achieved.
Simple Switch
OSTO® can be used as a ‘like for like’ replacement for traditional lightweight aggregates that are normally used in concrete.
This ‘drop-in’ solution is a game changer for a hard-to-abate sector like construction as it can greatly reduce the carbon footprint of projects in which it is used with a simple switch.
